For the last two days I have been unable to access localhost on any browser, after 6 months of problem free use. I have:

removed my antivirus, tried re-installing xampp,edited the windows32/drivers/etc/hosts file, checked for any other application using port 80uninstalled anything that was installed around the date xampp stopped workingtried 127.0.0.1/webfolder

and am now at a loss what to do next. When I type 'localhost/webfolder' in Firefox it defaults to 'http://www.localhost.com/' and in Chrome it tries to go to 'http://www.localhost/'
